I'm not seeing any materials when I use it unless I select one surface at a time manually from the Studio Viewport, the LuxRender materials list is always empty. I can't modify the surfaces other than change the presets, and sometimes it renders with textures, sometimes it doesnt, it also doesn't kick off LuxRender by itself.

I'm using LuxRender 8.4, Windows 7 64 bit and Daz Studio 3.1.2.32 for 32 and 64 bit. My system has 12 GB RAM
